Question

Position-time graph of a body is given below.v₁and v₂ are velocities at t₁and to. The slope of the line joining P and Q gives
a.average velocity b/w t1 and t2
b.v1
c v2
d.v1+v2/2​

Answer 1

Answer:

The slope of the distance - time graph gives the speed of the object.

For the particle A, the slope of the line is tanθ 1

=tan30= 31

For the particle B, the slope of the line is tanθ 2

=tan60= 3

Thus, ratio of the velocities, v BBv A

= tan60tan30

= 321/ 3

= 31

So, the ratio is 1:3
